RADIATOR CAP.

This invention relates to acapforradiators, used in connection with internal combustion engines, and one of the objects of my invention is to provide a radiator cap which can be used in connection with any style of radiator stem.

Another object of my invention is to provide a radiator cap that is not only highly ornamental, but one that can be quickly and easily operated for the purpose of filling the the radiator.

My invention will be readily understood after reading the following specification, taken in connection with the annexed drawing, wherein:

Figure 1, is a part elevational and sectional view of the cap with one of the arms slightly removed from its normal position.

Figure 2, is a plan view of the cover of the cap.

Figure 3, is a fragmentary view of the body portion of the cap, indicated by the arrow 3.

Figure 4 is an end view of the detached arm shown in Figure 1 looking in the direction of the arrow 4.

Figure 5 is a fragmentary view of a modified form of adapter shell, used in connection with the body of the cap.

Figure 6, is a fragmentary sectional view of a modified form of attaching the arm to the cover and body.

In the drawing 1, is the body of the cap, the

outer surface of which has thereon some ornamentation 2. Preferably made integral with the body 1, is a set of ribs, arranged diametrically opposite. These ribs 5 and 6 are, in the form shown in Figures 1 and 3, spaced apart, thereby providing a channel 7 betwen them, the purpose of which will be later pointed out. Fastened to the interior of the body 1, is an adapter shell 3, fitting against a shoulder 4, and removably held in place by any suitable means, as by set screw 8. The adapter 3, is threaded at 9, to fit on the stem of a radiator.

On certain makes of radiators an internal thread is required, on the cap, while on others an external thread is required, and when an internal thread is used on the radia tor stem, then the adapter is made as shown in Figure 5. From the structure shown in Figures 1 and 5, it will be apparent that the adapter 3, may have the threaded portion made to any given diameter, to fit any style ofradiator stem so that the body portion of tioning the portion 15 between and against the ribs 5 and 6. The lower part of the portion 15 is preferably enlarged as indicated at 16 and is circular in form to fit a groove 1'? in the lower end of the ribs 5 and 6, whereby the arm 14 may be pushed downward so that the part 16 snaps into the groove 17 and is held there under the resilient tension of the gasket 18, which is preferably held in position in an annular groove in the cover 10. The ribs 5 and 6 are preferably provided with ornamental bosses 19, through which fastening means, such as rivets are passed which also pass through the portion 15 of the arms 14 on the left side of Figure 1. This particular arm is therefore permanently fastened in position to the body 1, while the other arm is adapted to be unlocked so the arm and cover 10 can be swung over to uncover the opening into the cap.

The top part of the cover 10 is preferably provided with a surface 20, and a hole 21. to receive a Boyce motometer or some other device or ornamental figure.

In Figure 6, I have indicated a modified form of holding the left hand arm or wing 14 in position. In this modification a portion 15 is provided with a shoulder part 22 which cover for the body. and a gasket fitting between the cover and body, said body having exterior ribs diametrically disposed. each set of ribs being spaced apart to form a channel arms pivotally anchored to said cover and having portions fitting within said channels, means for permanently fastening one arm portion to its associated ribs and means for quickly detachably holding the'ot-her arm portion to its cooperating ribs.

2; A radiator cap comprising; a bodyportion having means to fit a radiator stem, a cover for the 'body and a gasket fitting be-V tween the cover and body, said body having exterior embossed ribs diametrically disposed, each set of ribs being symmetrically arranged andspaced apart to form channels, ornamental arms plvotally anchored to said ,cover and having portions fitting Within and portions having apart to fit over the ends of 20 its associated ribs to quickly detachably hold one of said arms 1n normal position,

In testimony whereof, I affix my signature.
